SLUUBT5C November 2018 – June 2021 BQ40Z80
When a high-to-low transition on the SHUTDN pin is detected with a debounce delay of about 1 s for the low level threshold, the gauge will turn off the CHG and DSG FETs immediately. This entry method only applies if [NR] = 1 and DA Configuration[EMSHUT] = 1. If [NR] = 0, the SHUTDN pin will restore to the regular system present detection.
